1 is a perspective view showing a state in which the cold storage room 100 according to the present invention coupled to the wall surface 150, Figure 2 is a cold storage room 100 according to the present invention coupled to the wall surface 150 It is sectional drawing which shows the state.

As shown, the cold and cold storage room 100 according to the present invention has a storage space formed therein, the body 110 is open at one side, the door 120 for opening and closing the open area of the body 110, and It is coupled to the body 110 includes a refrigerant driving unit 130 for driving in a refrigerant compression method, and a thermoelectric drive unit 140 coupled to the body 110 to drive in a thermoelectric method. Here, the body 110 is coupled to the space formed in the wall surface 150 of the room (Room) to be installed in the cold storage room for the room of the present invention, the area protruding to the outside is minimized to not reduce the width of the room It also looks beautiful. In addition, an air passage 151 is formed on the wall 150 to allow air to circulate better.

The body 110 has a substantially hexahedral shape with one side open. That is, the body 110 includes upper, lower, left and right sidewalls 111, and a rear wall 112 blocking the sidewalls 111. Since the body 110 is formed of a heat insulator or the like, the cold or warm air inside is not easily leaked to the outside.

The door 120 serves to open and close the front of the body 110. That is, the door 120 is installed in front of the body 110 is installed so that the user can open or close.

The refrigerant driving unit 130 is installed outside the body 110 to condense the refrigerant, a compressor 132 for compressing the refrigerant connected to the condenser 131, and the body of the 110 It is installed inside and is connected to the condenser 131 and the compressor 132 is composed of an evaporator 133 to evaporate the refrigerant.

The thermoelectric driver 140 is connected to the heat dissipation plate 141 installed outside the body 110 and the heat dissipation plate 141 to dissipate heat toward the heat dissipation plate 141 and absorb heat to the other side. An element 142 and a heat absorbing plate 143 installed inside the body 110 and connected to the thermoelectric element 142 are formed.

On the other hand, the body 110 is coupled to the space formed on the wall surface 150. In addition, an air passage 151 is formed on the wall surface 150 in contact with the body 110. The condenser 131 of the refrigerant driver 130 is positioned in the air passage 151, so that condensation of the refrigerant occurs more efficiently. In addition, since the heat sink 141 of the thermoelectric driver 140 is positioned in the air passage 151, the efficiency of the thermoelectric element 142 is further increased. In addition, since at least one blower fan 152 is positioned in the air passage 151, the blowing efficiency of air is further improved.

In addition, since at least one blowing fan 113 is positioned inside the body 110, the refrigeration efficiency or the warming efficiency is further improved.

Figure 3 is a front view showing the components installed on the rear wall 112 of the cold storage room 100 according to the present invention.

As shown, the evaporator 133 for evaporating the refrigerant in the refrigerant driving unit 130 is installed on the rear wall 112 of the cold storage 100 in the form of a pipe bent approximately several times. In addition, the heat absorbing plate 143 of the thermoelectric drive unit 140 is installed on the rear wall 112.

Of course, the heat absorbing plate 143 absorbs heat when the function of the refrigerator is implemented, but emits heat when the function of the warmer is implemented. In addition, the evaporator 133 does not operate at this time.

4 is a block diagram showing the electrical configuration of the cold storage room 100 according to the present invention.

As illustrated, the cold storage 100 according to the present invention includes an operation switch 161 for selecting one of a manual mode and an automatic mode, a temperature sensor 162 for sensing a temperature inside the body 110, and A clock sensor 163 for providing time, a door opening / closing counter 164 for detecting the number of opening / closing of the door 120, the operation switch 161, the temperature sensor 162, the clock sensor 163, and A control unit 165 for receiving at least one control signal from the door opening and closing counter 164 and controlling at least one of the thermoelectric element 142 and the compressor 132, and the compressor 132 by the control signal of the control unit 165. ) And a thermoelectric driver 140 for driving the thermoelectric element 142 according to a control signal of the controller 165.

The operation switch 161 serves to allow a user to select a manual mode or an automatic mode. That is, the user may manually drive the refrigerant driver 130, drive the thermoelectric driver 140, or drive both the refrigerant driver 130 and the thermoelectric driver 140. In this case, the thermoelectric driver 140 is in a refrigeration driving state. In addition, a user may manually stop the driving of the refrigerant driver 130 and may drive the thermoelectric driver 140 in a warm state.

The temperature sensor 162 detects a temperature inside the refrigerator, converts it into an electrical signal, and informs the controller 165.

The clock sensor 163 substantially informs the controller 165 of current time information. For example, the controller 165 notifies whether the present time is daytime or nighttime (sleeping time).

The door opening and closing counter 164 counts how often the door 120 is opened and closed for a predetermined time and informs the controller 165 of this.

The controller 165 receives signals from the operation switch 161, the temperature sensor 162, the clock sensor 163, and the door opening / closing counter 164, and performs arithmetic, storage, and control processing in a predetermined order. The controller 165 may be any one selected from a general micro-computer, a programmable logic controller, and the like. However, the type is not limited here.

The refrigerant driver 130 refers to the condenser 131, the compressor 132, and the evaporator 133 as described above, and may mean a power supply unit for substantially driving the compressor 132.

The thermoelectric driver 140 may refer to a power supply for driving the thermoelectric element 142 as described above.

5 is a block diagram showing a manual mode of the operation method of the cold storage room 100 according to the present invention.

As shown in the present invention, when the operation switch 161 is operated in the manual mode, it is possible to select the refrigerator mode, the warming-up mode, or the sleep mode.

More specifically, after the refrigerator mode is selected, the weak refrigeration mode for operating only the thermoelectric driver 140, the medium refrigeration mode for operating only the refrigerant driver 130, and operating both the thermoelectric driver 140 and the refrigerant driver 130. Either of the cold storage modes can be selected. Of course, all refrigeration modes are then approximately 10 degrees Celsius or less.

In addition, when the warmer mode is selected, the heat absorbing plate 143 of the thermoelectric driving unit 140 changes the role of the heat sink 141, the heat sink 141 is changed to the heat absorbing plate 143. This is because power of opposite polarity is input to the thermoelectric element 142. Of course, at this time, the refrigerant driver 130 stops driving. Therefore, in the warm-up mode, the body 110 maintains a room temperature (eg, 60 degrees Celsius or more).

In addition, after the sleep mode is selected, the thermoelectric driving unit 140 operates only in the weak refrigeration mode. Therefore, the refrigerant driver 130 is not operated, thereby minimizing noise and minimizing power consumption. Of course, since the user does not open the door while sleeping, sufficient refrigeration efficiency can be obtained only by the operation of the thermoelectric drive unit 140.

6 is a block diagram showing an automatic mode of the operation method of the cold storage room 100 according to the present invention.

As shown in the figure, any one of the temperature mode, the clock mode, and the door opening / closing mode may be selected while the operation switch 161 is operated in the automatic mode. Of course, the temperature mode, the clock mode and the door opening and closing mode may also be selected automatically or manually.

First, if the temperature mode is selected by an automatic or manual input method, the weak refrigerating mode in which only the thermoelectric drive unit 140 is operated according to the temperature input from the temperature sensor 162 described above, and only the coolant drive unit 130 is operated. Any one of the refrigeration mode and the strong refrigeration mode in which the thermoelectric driver 140 and the refrigerant driver 130 are operated at the same time is performed. For example, if the temperature of the cold storage 100 is below zero degrees Celsius, only the thermoelectric drive unit 140 operates, so that the power consumption is the minimum amount. In addition, when the temperature of the cold storage 100 is approximately 10 degrees Celsius or less, only the coolant driving unit 130 is operated to achieve an average power consumption and to quickly lower the desired temperature. In addition, when the temperature of the cold storage 100 is approximately 10 degrees Celsius or more, the thermoelectric drive unit 140 and the coolant drive unit 130 are both operated to be lowered to the desired temperature as soon as possible. Here, all the temperature ranges are for the understanding of the present invention, and the present invention is not limited to these temperature ranges.

Secondly, if the clock mode is selected by an automatic or manual input method, only the thermoelectric driver 140 is operated according to the time information input from the clock sensor 163 described above, the thermoelectric driver 140 and the refrigerant driver are operated. Any one of the strong refrigeration mode in which the 130 is operated simultaneously and the medium refrigeration mode in which only the refrigerant driving unit 130 is operated is performed. For example, if the current time is between 10 pm and 6 am (normally when the refrigerator door is hardly opened as a sleeping state), only the thermoelectric driver 140 is operated, so that the power consumption is minimized and the noise is driven quietly. To be In addition, if the current time is from 6 am to 9 am or from 6 pm to 9 pm (normally the refrigerator door is most frequently opened), the thermoelectric driver 140 and the refrigerant driver 130 may be By allowing all to operate as soon as possible the temperature of the cold and cold storage 100 is lowered to the desired temperature. In addition, if the current time is between 9 am and 6 pm, the coolant driver 130 operates, so that the average power is consumed. Here, all the time ranges are for understanding the present invention, and the present invention is not limited to these time ranges.

Third, if the door opening and closing mode is selected by an automatic or manual input method, the weak refrigerating mode in which only the thermoelectric drive unit 140 operates according to the number of opening and closing of the door 120 input from the door opening and closing counter 164, Any one of the medium refrigeration mode in which only the refrigerant driver 130 is operated and the strong refrigeration mode in which the thermoelectric driver 140 and the refrigerant driver 130 are operated simultaneously are performed. For example, when the number of opening / closing times of the door 120 per hour is less than one time (normally in a sleeping state), only the thermoelectric driving unit 140 operates so that power consumption is minimized and low noise driving is performed. In addition, when the number of opening and closing times of the door 120 per hour is 1 to 5 times, only the refrigerant driving unit 130 operates so that the average power is consumed while the temperature of the cold storage cell 100 is lowered to a desired temperature. . In addition, if the number of opening / closing times of the door 120 is 10 or more times (normally during breakfast or dinner preparation), the thermoelectric drive unit 140 and the coolant drive unit 130 may both operate to operate the cold and hot store as soon as possible. The temperature of 100 is lowered to the desired temperature range. Here, the opening and closing frequency ranges of the door 120 per hour are all for the understanding of the present invention, and the present invention is not limited to the opening and closing frequency range of the door 120 per hour.

In addition, the operation mode according to the time and the operation mode according to the number of opening and closing may be appropriately mixed to be controlled.

Cold and cold storage according to the present invention as described above by adopting the thermoelectric element and the compressor at the same time, not only the high cooling and heating efficiency, but also the power consumption is reduced, and in particular, the quiet operation at night with less use, so that the sound sleep This can minimize interference.

In addition, the cold and cold storage according to the present invention is provided with a temperature sensor, a clock sensor and a door opening and closing sensor to automatically refrigerate and warm up by operating the thermoelectric element and / or the compressor automatically or individually according to a predetermined temperature, a predetermined time or a predetermined number of door opening and closing. Not only is it more efficient, it also minimizes power consumption.

What has been described above is just one embodiment for carrying out the cold and hot storage according to the present invention, the present invention is not limited to the above-described embodiment, and as claimed in the following claims deviate from the gist of the present invention Without this, anyone skilled in the art to which the present invention pertains will have the technical spirit of the present invention to the extent that various modifications can be made.

In addition, although the present invention is referred to as a cold storage cell for a room because it is an effective cold storage cell as a cold storage cell, especially when used in a guest room, it is obvious that this is not compulsory to be used in the guest room.
